Hi All. I have a LL installed on cluster. The problem is that LL does not consider the used CPU Time for tasks that run on the command mpirun. Although normally considered when working for example with ANSYS. Settings made on the user's manual correctly.
Any help?

Re: Tivoli LoadLeveler accounting question

Was your mpirun command built using "llspawn.stdio" as the remote shell program?

If you are using rsh or ssh to spawn remote tasks, LoadLeveler will not be able get accounting information on slave nodes.
It will only report the usage of the mpirun process.

If Intel MPI allows us to specify the remote shell command to use (for example, mpiexec -r <rshcmd>), you could try specifying llspawn.stdio as the remote shell command. As you already know, this is not supported by LoadLeveler.
